Lette/rs Patent No. 93,930, dated August 17, 1869.

IMPROVED SHUTTER-FASTEN IN G.

The Schedule referred to in these Letters Patent and making part of thesaune.

To all whom (it may concern:

. 'Be it known that I, Amos Wnsroor'r, of the city of Syracuse, in thecounty of Onondaga, and State of New York, have invented a newandimproved Catch for any small double doors; and I do herebydeclarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon.

This invent-ion relates to a fastener for windowshutters,cupboard-doors, and otherdevices requiring to be held in an open orclosed position.; and

It consists in the combination of the partsof which it is composed,as-'will be more fully described hereinafter.

lo enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation. v

I construct avmetal face-plate, marked A, Figure 2, of any convenientsize and shape, which I fasten to the inside, and near its front edge,of that one of a pair of' small double doors which isV .closed first, asshown by A in Figure j A Freni a small hole in the centre of thisface-plate A, fig. 5, .there projects inwardly a stem, markedG, moreclearly shown by the same letterin iig. 2, terminating at its inner endin a hook, which, when the door is closed, catches into a notch, orother equivalent holding, underneath, and near the frontedge of a shelf,as represented by M, iig.

rIhis 'stem i's attached at its outer end to the centre of a lever onthe other side of the faceplate,.as more clearly shown in Figure 4.

A little at one side of this stern G, fig. 5, or more generally a littlebelow, projecting inwardly through a hole in the face-plate A, is asmall knob or projection, marked H, iig. 5, which is fastened to orforms a part of one arm of. a lever on the other side of the faceplate,shown more clearly in iig. 4, and which, when pressed in, releases thehook from its holding.

In Figure 1 is represented the reverse side of the face-plate A, g. 5,with its attachments.

From the centre of this side of the face-plate A, iig.

:1, rises perpendicularly a hollow post, marked C, fig. 1 more clearlyshown in Figure 3slotted from its top to near its base, or to thesurface of the face-plate, the slot being about equal in width to theknob H, iig. 4, and its sides in line with the sides of the hole, markedS, lig. 3, through which the knob H projects.

In this slot, and'. at right angles to the post, is placed theirregular-shaped lever, marked E, iig. 1, more clearly shown in iig. 4,and secured in its place in this slot by the pin I, lig. 1,-which formsthe fulcrum about which the lever can turn as far as required.

Upon the other side of the post O, fig. 3, opposite the hole S, tig. 3,there rises from the surface of the faceplate, perpendicular thereto,the pin, marked B,

tig. 3, far enough to reach through a hole in the other arm of thelever, marked F, figs.1 and 4. g

Underneath this arm ofthe lever, `and surrounding theV pin B, is a smallspiral spring, marked K, fig. '1, which all the time tends to press thearm F ofthe lever away from the surface of the face-plate A, as shown innge-1.

It will readily be observed, 'from the above descrip.- tion, that whenknob H, tig. 2, is pushed in, the amr of the lever E, to which it isattached, will be raised from the surface'of the face-plate A, g. 1, andthe other arm ofthe same lever, marked F, iig. 1, will-be brought nearerthe surface of the face-plate, and the stem G, fig. 1., will be releasedfrom the holding, marked M, iig. 5, and the door to which it is attachedcan be opened. v

What I claim as my invention, and desire to secure by Letters atent, is-

The combination of the lever E, havingthe projections lF G H, whenpivoted upon the projection G cast upon the plate A, and spring K, allconstructed and arranged to operate substantially as and for the purposespecified.
